So I just picked up an Sound Blaster Audigy 2 ZS sound card for my computer hoping that the hum I had would go away. Well it is still there and I can't figure out why. I am going nuts, I don't know if it is my computer or my cables or what. If I plug my headphones into the computer I get no hum from them. I try to play it on my system, no luck, I still got a hum in the backround. So if I try to turn it up it sounds like ****. Whats going on here, somebody please help me!:(

    Break it down to the basics. Unhook DVD, CD, extra fans, etc. and start from there. You smell what I'm cookin?

    You mean un-hook things in my computer? I don't think that is a very good idea, not something I should be doing.

    What speakers are you using with your computer?

    Well, if you don't want to unhook anything.... You could go buy the cheapest computer speakers you can find, connect them, and see if the problem is still there. That would at least eliminate one thing.

    I used to have a hum when I had a long run connecting my computer through my vcr. I moved my computer next to my TV (same outlet), and connected it through my TV, I don't have a hum anymore. I have no clue why the hum went away.

    I would try the following:

    1) Plug computer and receiver in the same outlet

    2) disconnect everything from the receiver except the computer

    3) move things so there is a short run connecting the computer to the receiver

    4) use a different/better interconnect

    5) disconnect and turn off you computer monitor (after you are up and running, to see if the hum goes away).

    6) Disconnect TV cable from computer (if you have it connected)

    7) Disconnect any other external devices attached to your computer.

    I'm beginning to think its my soundcard. I tried a bunch of stuff that eliminated the cables, so I THINK the cables are out. And forget about the no hum with the headphones, it is still there.

    I just picked up a cable so now I know it is not the cable. I am going to have my computer looked at tommorow.

    Have you tried a ground loop isolator? I was having the same problem when playing music from the comp. I can't remember where I heard about the isolator (probably on this forum), but it worked, and now no more hum :) I picked one up from the car audio section at Wal-mart for a few bucks, but I'm sure you could find them elsewhere.
